Manufacturing standard of marble Square: manufactured according to gb6092-85 standard. In order to reduce the weight of the marble square rule and facilitate its use, holes are made on both sides of the square rule without affecting its structural stability. In this way, even in the inspection operation, the self weight of the marble square is reduced, and the inspection engineer is easy to handle
specification of marble Square: (length * width * height) 200*200*35 250*250*40 315*315*45 400*400*50 500*500*60 (special specifications can be customized)
accuracy of marble Square: according to_ The standard is divided into class 00 and Class 0
